EDIBLE FROG. 113 
I gave a figure of this species in the former edition 
of the present work, taken from a foreign specimen, but 
I have thought it better to have the present illustration 
taken from an individual which is a native of the British 
locality before referred to. The figure above referred to 1s 
repeated below: it will enable the reader to compare the 
English with the foreign variety. 
The following notice, in a recent number of the ‘‘ Zoo- 
logist,” * shews that the extension of this fine species

The peculiarities both in habits and appearance which 
characterize this species in England, agree, as far as they 
have been observed, with those mentioned by Dumeril and 
Bibron, and other continental authors. ‘“‘ It is,” say these 
eminent naturalists, “essentially aquatic. It inhabits in- 
discriminately running or still waters, the borders of rivers, 
rivulets or streams, lakes or ponds, salt or fresh marshes, 
or even ditches and simple pools of water. Sometimes 
they are seen on the leaves of water-lilies, or on the herb- 
age of the banks, where they love to bask in the warm 
sunshine; but at the slightest noise they strike into the 
water, and do not again expose themselves until certain 
that all danger is past. 
The croaking of the male is exceedingly powerful, and 
is produced by means of the air which it forces into the 
globular vocal sacs, which are situated near the corners of 
the mouth, and causes to vibrate in them; they croak
